I've been a major Sony fan for ten years. I grew up with the PlayStation. I loved its games and its franchises. But when it came to the new generation, I decided that although MGS and FF are great series, I wanted to try new games. Halo, Gears of War, and the game I bought my console for, Dead Rising.
Three months on, I can say I think it was an absolutely great decision on my part. Xbox Live is a glorious, GLORIOUS thing, and I had never anticipated it being like that. I still have a faint glimmer of hope that Konami will release MGS4's subsistence equivalent for the 360, but I'm not expecting it. Still, I'm more than happy with what I have!
